Shen Qing learned that the martial arts in the county could be roughly divided into three levels: upper, middle, and lower.
The lowest level of martial arts, like the "Nine Skills," only nurtured and trained Qi and Blood.
Such martial arts offered no other techniques, training methods, or killing techniques; it was the foundation of foundations in martial arts.
Even so, this martial art was still stronger than those flashy but useless tricks.
As long as enough Qi and Blood were cultivated to reach the realm of Great Perfection, even a slender person could knock down four or five strong men with a single punch.
If martial arts did not have such power, they would not be so valuable, nor would the court impose such strict regulations.
The people in power feared most that someone in a place would leverage martial strength to defy authority.
